Applications
The HP 4951C is a portable protocol analyzer introduced in the mid-to-late 1980s for testing synchronous and asynchronous serial data communications links, including RS-232, V.35, and X.25 WAN interfaces. It was widely used by telecommunications engineers, data communications technicians, and network installers to capture, decode, and troubleshoot serial protocol traffic on leased lines and WAN connections. The 4951C could emulate DTE or DCE, generate test patterns, and decode multiple protocols, making it a versatile field and lab instrument for its era. This operating manual would have accompanied new units and was the primary reference for setup, operation, terminal emulation, and protocol configuration — including the Terminal Setup and Getting Started sections visible in the interior photos. Original HP documentation from this period is sought by technicians still supporting legacy serial infrastructure and by collectors of HP test equipment.
This HP 4951C Protocol Analyzer Operating Manual (part no. 04951-90753) has been inspected and shows water damage. The moisture has caused a number of pages to stick together, and we have not attempted to separate them. The cover and binding are intact, and the manual is otherwise structurally whole, but the stuck pages mean some content may not be fully accessible without careful handling. The page warping from moisture is visible throughout. Please review our photos carefully before purchasing, as they show the full extent of the water damage. Please view our photo set and contact us if you have any questions.
